@HSZ Thank you very much for reply. Is there any particular reason why LCN-PRO allows to assign more variables such TS(3), TS(4) just as it does for GBL(2-4)? Are these remainings of older possibilities of system? Or these are supposed to be updated externally from other modules? LCN-TS description says it is digital sensor while this limitation seems to be specific to analog devices using resistance for value reporting. I know GBL is more compelx and most likely have bigger chip mounted on board, but such hard limitation for most basic function everyone desires is quite surprising. Are these any plans to make temperature sensing cheaper with LCN?
@Thomas Regarding onewire, I do have few onewire items mounted in utilities room where designer didn't put any LCN module and pulled in via USB plugged into RPI and then integrated via openhab (where I do plug also LCN via PCHK so I have read/write access to bus). It is quite pity that such expensive sensors can not be chained into bigger network especially that they have one more wire than 1wire. Single LCN-TS (30€) could be sufficient to supply my whole house with DS18B20 (3€ or even less).
I had a project from authorized installer who get paid for visit and did plan one module for 2 rooms+corridor and according to his sketch and words "with LCN everything is possible". Obviously he must have had some other idea for pulling in temperature from these two rooms. Since wires were made from sensors to UPP mounting place I can not change them. Pulling in GBL for 80€ which cost twice as much as already bought TS makes no big sense for me, especially that these rooms supposed to be "twins"/mirrored. Mounting another UPP/UPS for 100+€ just to read data from single TS doesn't sound reasonable from cost perspective too.
Kind regards,
Lukasz
